The Toyo Cleanroom Series Modules are precision linear motion products designed by TOYO specifically for clean environments. They are divided into three main series: GCH (steel belt type), ECH (screw type), and ECB (belt type). All have passed SGS certification and meet CLASS10 cleanliness standards; with an external vacuum source, they can reach CLASS1 level. They are widely used in fields with strict cleanliness requirements such as semiconductors, medical care, and food.

II. Evaluation of Core Advantages
Cleanroom Performance
Enclosed structure: Prevents external particles from entering; internally generated dust is discharged through the air suction nozzle
Negative pressure enhancement: External vacuum source can upgrade cleanliness from CLASS10 to CLASS1
Material selection: Uses low particle-generating materials, strictly tested and certified by SGS
Accuracy and Stability
ECH Series: ±0.005mm accuracy, meeting the requirements of semiconductor wafer-level inspection
Multi-axis synchronization: Supports multi-axis linkage control with positioning accuracy reaching ±0.1μs phase error
Thermal stability: Special design reduces thermal deformation, ensuring long-term operation accuracy
Operational Performance
High-speed response: Maximum acceleration of 3G, significantly shortening production cycles
Low noise: Operating noise below 60dB, improving the working environment
Energy efficiency: Consumes electricity only during movement, almost no energy consumption when stationary
Installation and Maintenance
Quick installation: GCH Series can be fixed without removing the steel belt, saving 50% of installation time
Maintenance-free: The steel belt drive of GCH Series has a long service life and requires almost no maintenance
Easy to clean: Smooth surface without gaps, facilitating cleanroom cleaning
III. Practical Application Scenarios
Semiconductor Industry
Wafer inspection: The ±0.005mm accuracy of ECH Series ensures that inspection equipment can accurately capture micron-level defects
Packaging equipment: The low particle generation characteristics of GCH Series prevent chip contamination and have been applied in production lines of TSMC, ASE, etc.
Actual effect: In a certain packaging and testing factory, Toyo modules increased inspection efficiency by 40% and reduced the defect rate to 0.02%
Lithium Battery Manufacturing
Pole piece coating: The high load (85kg) and long stroke (3500mm) of ECB Series support the stable operation of large coating equipment
Battery cell assembly: The high precision of ECH Series ensures that the tab welding position error is <±2μm, increasing the yield rate to 99.2%
Medical Equipment
Precision surgical instrument assembly: The cleanliness and low vibration characteristics of GCH Series ensure instrument precision
IVD equipment: Clean environment prevents reagent contamination, ensuring detection accuracy
Food Packaging
Pharmaceutical sorting: The high speed (2000mm/s) and silent characteristics of ECB Series improve packaging efficiency and reduce noise pollution
Clean environment: Prevents particle contamination during food processing, meeting GMP standards
IV. Usage Notes
Installation direction:
ECB Series is strictly prohibited from vertical use, otherwise the belt will fall off
GCH/ECH Series have no such restrictions and can adapt to various installation angles
Cleanliness management:
Before use, confirm the cleanroom pressure difference (clean area and non-clean area ≥10Pa)
Regularly check the air extraction system to ensure normal negative pressure (weekly inspection is recommended)
Selection guide:
Light load and high speed → GCH Series
High-precision positioning → ECH Series
Long stroke and heavy load → ECB Series (for horizontal use)
V. Summary and Purchase Recommendations
Toyo Cleanroom Series Modules have established significant advantages in the field of clean automation with low particle generation, high precision, and high reliability, making them particularly suitable for high-end manufacturing scenarios sensitive to the environment. Choose the appropriate series according to actual application needs: For semiconductors and medical equipment, prioritize the ECH Series (accuracy first); for lithium batteries and large production lines, recommend the ECB Series (cost-effective); for lightweight high-speed applications, the GCH Series (easy maintenance) is optional.
For further understanding of product performance, it is recommended to contact TOYO official to obtain detailed technical specifications or apply for sample testing to verify their actual performance in specific application scenarios.
